Abstract
The aim of this work is to analyze a typical
configuration of a Wind Turbine Generator System (WTGS)
equipped with a Variable Speed Generator. Nowadays, doublyfed
induction generators are being widely used on WTGS,
although synchronous generators are being extensively utilized
too. There are different types of synchronous generators, but the
multi-pole Permanent Magnet Synchronous Generator (PMSG) is
chosen in order to obtain its model. It offers better performance
due to higher efficiency and less maintenance since it does not
have rotor current and can be used without a gearbox, which also
implies a reduction of the weight of the nacelle and a reduction of
costs. Apart from the generator, the analyzed WTGS consists of
another three parts: wind speed, wind turbine and drive train.
These elements have been modeled and the equations that explain
their behavior have been introduced. What is more, the whole
WTGS has been implemented in MATLAB/Simulink interface.
Moreover, the concept of the Maximum Power Point Tracking
(MPPT) has been presented in terms of the adjustment of the
generator rotor speed according to instantaneous wind speed.
